Resumen

We have measured the temperature dependence of Young's modulus (E) of the quasi-one-dimensional conductor Nb₃Te₄. ΔE(T) E₀ increases its slope sharply at T₁ ∼ 95K, the commensurate charge density wave (CDW) phase transition. The existence of hysteresis in T₁ confirms that this transition is first-order. A more dramatic anomaly, with a dip in relative modulus of 3×10^-3 has been observed at T₂ ∼ 40K, which is possibly due to another (second-order) CDW phase transition. Peaks in the internal friction have also been observed at these temperatures, but they are two orders of magnitude smaller than the relative changes in E.
